You may have heard that the tide comes in and the tides goes out, but in fact a tide is the vertical movement of water toward the moon and only goes up and down. Current is the horizontal or sideways flow of water. The current floods in which makes the tide rise and ebbs out which makes the tide fall. A tide is the rise and fall of water caused by gravitational forces of the moon and sun on the oceans of the earth.

How do the movements of the sun and the moon affect tide? The gravitational pull of the moon tugs on the surface of the ocean until its surface mounds up and outward in the direction of the moon. When the mound of water has reached its highest point it is called high tide. On the opposite side of the earth from the moon, the centrifugal force caused by the earth's rotation produces another mound of water and high tide. Between these two high tides are two flat areas on the surface of the ocean which are the low tides.
so basically the moons gracitation pulls the water towards the moon causing tides
